It works, just more as easily as it should. Mine was phone for ages. I
got it working after I removed an additional home I had set up in my
Google Home, then reset the camera and redid the set up process in
Google/Nest
It is worth trying to get it to work if you have a Google home and
associated devices. And it is possible to get it working. I got mine
working when I had the same "offline" issue.
I was able to resolve it, yeah. I had to delete a second "home" I had
set up in the app (my parents house) and then I did a factory reset. Has
been working since
